Simple Code Examples

C#

// Declare using statement 
using MBClient = AutomatedSolutions.ASCommStd.MB.Client;

// This function creates all required ASComm objects sets initial properties, performs a write and read, then disposes the ASComm objects  
void SimpleReadAndWrite()  
{  
  // Create a Channel  
  MBClient.Net.Channel myChannel = new MBClient.Net.Channel();  

  // Create a device at IP Address 192.168.0.171  
  MBClient.Device myDevice = new MBClient.Device("192.168.0.171");  
  // device uses Modicon 5-digit addressing  
  myDevice.AddressType = AddressType.MODICON_5_DIGIT;  

  // Create Group with active flag set to false (no background scanning).   
  MBClient.Group myGroup = new MBClient.Group(false, 500);  

  // Create an item that represents one holding register at address 40001  
  MBClient.Item myItem = new MBClient.Item("40001", 1, TagType.HOLDING_REGISTER);  

  // Add device to channel  
  myChannel.Devices.Add(myDevice);  
  // Add group to device  
  myDevice.Groups.Add(myGroup);  
  // Add item to group  
  myGroup.Items.Add(myItem);  

  //Write one tag  
  try  
  {  
    // Perform a write with value from text box  
    myItem.Write(textBoxItemWrite.Text);  
  }  
  catch (Exception ex)  
  {  
    // Error occurred, implement error handler  
  }  

  // Read one tag  
  try  
  {  
    // Perform a read, save value to text box  
    myItem.Read();  
    textBoxItemRead.Text = myItem.Values[0].ToString();  
  }  
  catch (Exception ex)  
  {  
    // Error occurred, implement error handler  
  }  

  // Dispose channel at application shutdown  
  myChannel.Dispose();  
}
